An alleged sexual assault by Los Angeles Laker guard Kobe Bryant began consensually, but quickly turned otherwise, sources said Wednesday.

Sources said Bryant asked the alleged victim, a 19-year-old Eagle woman, for a tour of the Lodge & Spa at Cordillera, which ended at his room, and that he invited her in.

Sources said that after she was inside they started "fooling around," and that it began consensually, but she quickly told him to stop.

"She was trying to leave and was not allowed to leave," one source told the Daily.

About 20 minutes later, the alleged victim returned to the hotel lobby in a shocked stupor, showing signs of physical injury, sources said. Bryant showed up in the lobby later that night to play chess, sources said.
